Answer:

x^2 + y - 3(x + 4)

Step-by-step explanation:

Do one thing at a time until you figure out the entire expression.

the sum of the square of a number x and a number y, minus the product of three times the sum of x and 4

the sum of the square of a number x and a number y, minus the product of three times the sum of x and 4

x^2

the sum of the square of a number x and a number y, minus the product of three times the sum of x and 4

x^2 + y

the sum of the square of a number x and a number y, minus the product of three times the sum of x and 4

x^2 + y -

the sum of the square of a number x and a number y, minus the product of three times the sum of x and 4

x^2 + y - (x + 4)

the sum of the square of a number x and a number y, minus the product of three times the sum of x and 4

x^2 + y - 3(x + 4)

What is the factored form of 343 + X6?

yan [13]

Answer:

Step-by-step explanation: 1.1 Factoring: 343-x6

Theory : A difference of two perfect squares, A2 - B2 can be factored into (A+B) • (A-B)

Proof : (A+B) • (A-B) =

A2 - AB + BA - B2 =

A2 - AB + AB - B2 =

A2 - B2

Note : AB = BA is the commutative property of multiplication.

Note : - AB + AB equals zero and is therefore eliminated from the expression.

Check : 343 is not a square !!

Ruling : Binomial can not be factored as the

difference of two perfect squares

Polynomial Roots Calculator :

1.2 Find roots (zeroes) of : F(x) = -x6+343

Polynomial Roots Calculator is a set of methods aimed at finding values of x for which F(x)=0

Rational Roots Test is one of the above mentioned tools. It would only find Rational Roots that is numbers x which can be expressed as the quotient of two integers

The Rational Root Theorem states that if a polynomial zeroes for a rational number P/Q then P is a factor of the Trailing Constant and Q is a factor of the Leading Coefficient

In this case, the Leading Coefficient is 343 and the Trailing Constant is -1.

The factor(s) are:

of the Leading Coefficient : 1,7 ,49 ,343

of the Trailing Constant : 1

Let us test ....

P Q P/Q F(P/Q) Divisor

-1 1 -1.00 342.00

-1 7 -0.14 343.00

-1 49 -0.02 343.00

-1 343 -0.00 343.00

1 1 1.00 342.00

1 7 0.14 343.00

1 49 0.02 343.00

1 343 0.00 343.00

Polynomial Roots Calculator found no rational roots

Final result :

343 - x6

Answer:

The value of x that maximizes the volume enclosed by this box is 0.46 inches

The maximum volume is 3.02 cubic inches

Step-by-step explanation:

see the attached figure to better understand the problem

we know that

The volume of the open-topped box is equal to

$V=LWH$

where

$L=(7-2x)\ in\\W=(2-2x)\ in\\H=x\ in$

substitute

$V=(7-2x)(2-2x)x$

Convert to expanded form

$V=(7-2x)(2-2x)x\\V=(14-14x-4x+4x^{2})x\\V=14x-14x^2-4x^2+4x^{3}\\V=4x^{3}-18x^{2} +14x$

using a graphing tool

Graph the cubic equation

Remember that

The domain for x is the interval -----> (0,1)

Because

If x>1

then

the width is negative (W=2-2x)

The maximum is the point (0.46,3.02)

see the attached figure

therefore

The value of x that maximizes the volume enclosed by this box is 0.46 inches

The maximum volume is 3.02 cubic inches
